Live Meeting For OS X
If you're running OS X, please skip step #1 and go directly to step #3 with Safari. For instructions on how to use Live Meeting within OSX, please refer to this KB article.
Since live meeting does not provide a great way for everyone to interact durring presentations we are going to use IRC (Internet Relay Chat) to do this. I know it is pretty old school, but I think it adds something that is missing from live meeting. So when you login please use the same name in the chat that you used in the live meeting.Webchat
